Energy Transformations and Light Flashcard Science TEKS 5.7A/B/C

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting chemical energy into electrical energy.

Front

What type of energy does a battery store?

Back

A battery stores chemical energy.

Front

What is the primary energy transformation in a flashlight?

Back

The primary energy transformation in a flashlight is from chemical energy to electrical energy to light energy.

Front

What is an electrical circuit?

Back

An electrical circuit is a closed loop that allows electricity to flow, consisting of a power source, conductors, and a load.

Front

What is a power source in an electrical circuit?

Back

A power source provides the energy needed to drive the current through the circuit, such as a battery or generator.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as copper wire.

Front

What happens when light passes through a glass of water?

Back

When light passes through a glass of water, it is refracted, meaning it bends as it enters and exits the water.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, such as from air to water.

Front

What is the role of a switch in an electrical circuit?

Back

A switch controls the flow of electricity in a circuit by opening (turning off) or closing (turning on) the circuit.

Front

What is the difference between electrical energy and light energy?

Back

Electrical energy is the energy of moving electrons, while light energy is the energy carried by light waves.
